To all whoma't may concern.

Be it known that I, LAWRENCE A. SUBERS, a citizen of the UnitedStates,and resident of East Cleveland, in the county of Guyahoga' and State ofOhio, have invented certain new and useful Improvements in Machines forConstructing a Laminated Cohesive Interwound Fabric Band, of which Ihereby declare the'following to be a full, clear, and exact description,such as will en- -able others skilled in the art to which it appertainsto makeand use the same.

The objects of the invention are to provlde efiic1ent and practicalmeans for forming an unwoven, laminated, cohesive, 1nterwound fabricband, consisting of yarn ele-' ments, and in coating and permeating theyarn elements and band with liquid rubber or other adhesive material,the yarn elements being interwound andlaminated upona preferably hollowtube or mandrel to form a fabric tube which is afterward collapsed.

to a band form, having a selvage edge, the rubber being preferablysolidified by evaporating the solvents contained therein,-by

exposing them upon suitable conveying devices to the drying influence ofthe atmosphere, or other drying agencies, so that the yarn elements andfinished band are sufli ciently treated with coating material for theadhesion desired, and for vulcanization if and coating, the preferredmanner of interw1nd1ng,lammat1ng, and coatlng the bands may be describedas follows:

First of importance are the mechanical means employed for interwindingand-laminating the yarn elements at any predetermined angle upon amandrel, so that the extensibility of the finished compressed band I canbecontrolled according to the angle at which the yarn elements arelaminated, as

for instance at 2,.4, 7, or 10 or'at a greater or less angle as may be.desired, or

a portion of the yarn elements may be laid parallel to'the mandrel bythe non-rotation of the .reel upon which the same are stored.

The mechanical means include specially designed and constructed reelswhich rotate about a hollow forming tube or mandrel,

alternate reels rotatingpreferably opposite directions, to i terw nd'andlaminate thereon, a series ofyarn elements, under a predetermined amountof tension. These yarn elements are stored on spools or tubes rotatablymounted on said'reels, said yarn elements being guided to and spacedabout the mandrel at equal intervals. A series of adjustable spacingdevices are important to the proper action of the machine and areemployed when constructing bands havingdifferentangles of interwinding.In forming these laminated, cohesive, interwound bands at various anglesby the several means herein described, slightly different forms ofmandrels or forming tubes may be required, the lengths and diameters ofthe several portions thereofyvarying according to the angle ofinterwinding' desired.

Further features of the invention consist in means for impregnating thefabric band with the coating material and which comprise preferably achamber'filled with the coatmg mater1al maintained under pressure V andthrough which the mandrel passes, and

force required. By nieans of this expansion the crossmg polnts of theyarn elements are changed, and also their normal angle to. the v Ilongitudinal axis of the mandrel is changed, so that the coating.material has access to every part.

Next in importance is a pulling device adapted to pull the fabric fromthe mandrel at a predetermined rate of speed relative to the rate ofspeed of the winding reels, and preferably consists of upper and lowermetal against the-tension of the yarns and against the resistance due tothe friction, upon the mandrel. .The' fabric band is' held between bandswhich move with the. fabric band the upper and lower metal bands, one orresilient pressure, and maintain a firm hold upon the band and preventthe distortion both of which are provided with projections and narrowingthereof under the pulling strain. Means are also provided for regulatingthe speed of the pulling devices, and separate means are employed forregulating the speed of rotation.) of the reels, thus providing twomethods of regulating the comparative rates of speed of the winding andpulling devices.

An important feature comprises a series of drums and rolls over which.passes an endless belt whose speed is so controlled that vthe fabricband is delivered theretowith comparatively no tension, whereby itsdesired width is maintained, and-,while being conveyed thereover, thelatter is exposed to the drying action of the air which partiallyevaporates the solvents in the coating ma terial. Means for quicklyextracting the re- .maining solvents and gases in the coating materialon the fabric band and which might necessitate long exposure to the airis provided by passing the fabric hand through a cham ber wherein apredetermined amount of heat desired.

and percentage of vacuum are maintained.

Also, according to the coating material to be treated, compressed air,or gas, or a mixture of gases with or without the application of heat orcold may be used therein to attain .the purpose desired. The solventswhichare evaporated from the coating material on the band and whichinthe case of liquid rubber compositions are reduced to gaseous formbythe action of the vacuum drying chamber, may. be allowed to escapefrom the exhaust of the vacuum pump or may be condensed by the usualmethod'and reclaimed,- as'may bedesired.

Means are also: provided forproducing a predetermined amount ofstretching of the ,fabric band so that its extensibility in a fabricmade'therefrom can be controlled as A hollow, flat mandrel permits thepassage of .a layer or ribbon of the adhesive material to the interiorof the fabric band, or a band 1 of metal or other flexible substance maybepassed therethrough, with or without a coattherefon:

5 ing compound tn the interior of the fabric band providing a-permanentreinforcement The invention also provides means by which an adhesivecoatmg of various compositions; maybe applied to the cdnstituentyarnsafter they have been interwound and laminated on'the mandrel andmeans for temporarily expanding the band to give access forthe'coatingto all theyarns, and finally means by which a coating. of still.different composition or material may be ap-v plied tothe outside of thefabric, band if desired.

a Finally the invention "includes means for the finished fabric bandupona suitable'reel'and for interwinding a band of non-adhesive materialto rotect the coils of Q the fabric band from a f .The invention furtherincludes the comering together. .1

In these drawings the construction and 7 operation of thereels is in allcases shown to be the same and is illustrated in Figs. 1, 2, 3, 4, 5, e,7, 8, 9, 10, and 11 in detail.

Here B, B, B andB are four reels arranged to rotate, 'one within theother,

about a central stationary standard B on' the frame B and supporting atube Y for the passage of fluid rubber therethrough'. Theinner reel B(see-Fig.3) is. mounted upon the rollers B secured in the arms of thestandard 13". Within the rollers B are secured the roller or ballbearings B to decrease the friction, thereby reducing thepower foroperation. The rollers are mounted upon spindles B The other reels aremounted upon rollers B B having ball bearings 13, B and rotating uponspindles 13, secured in brackets B upon the bracket or frame B Thespindles B and 13 upon which the rollers B and B rotate areeccentrically mounted to permit of fine adjustment of the reels so thatthey will operate in concentric paths. This ad justing means alsopermits of bringing the rollers B B and B B into' and out '-ofengagement with'the reels so that the reels can be easily put in placeor removed when desired. When .the rollers and reels are in engagementthe flanges 13 on the reels en gage shoulders B on the rollers and thereels cannot be removed until the eccentric spindles are turned. PlatesM, M, secure the outer ends of the. spindles B B Taper plugs B screwedinto the split ends of the eccentric spindles B B clampthem to plate M,so that they cannot turn when th machine is in operation. A ring gears Band B on the respective first andv third reels B andB and rotate themin-the same direction. The other reels, viz. the second'and fourth, Band B are rotated in the reverse direction by means of the maron theshort shaft B, the bevel .gear B on shaft B engaging gear 13 on theshort shaft B 9, bevel gears B and B thereupon -respe'ctively engagingthe marginal gear 13 on the second reel B and marg1nal gear-B on fourthreel B. Uponeach reel is mounted a predetermined number of rotatablespools C, C lipon which the yarn elements composing the band are, storedfor use.

.ginal gear B engaging the bevel gear 13 These yarn elements in thefabric described consist of flat strips composed of groups of looseyarns-lying parallel to each other and of a predetermined number anddiameterand are applied to the mandrel as the reels revolve about it,all the spools beingfilled with similar yarn elements composed of looseyarns equal in the number of yarns so that all the yarn elements whichcompose the band will be exactly alike. Thespools are adjustably securedto the reels by means of stems N slidingly movable in transverselygrooved bases N and clamping nuts .N as shown in Figs. 5, 7 8, 9 and 10,and

are spaced thereon in such a manner as to apply the yarn elements inequally spaced rows upon the mandrel, to form thelaminated-cohesive-interwound band. --In each spool theyarn elements arewound upon a tube N as shown in Fig. 5 which can be forced by lightpressure upon a special tube N? having one or more longitudinal slots Nand slightly expanded to provide the 1 "spring pressure to hold thespool C and having at each end self-lubricating bushings N N which bearon the stem N on which therefore the spool C rotates. arm N pivoted uponapro1ect1ng' end N A locking 7 of the stem N and engaged by apin 'Nvpressed by a spring N longitudinally securedin thestem N holds thespool G from coming off the stem N but when turned to the position shownin dotted lines Fig. 5

permits the spool and tube N to be-with-- Y drawn.

- Elongated guide rollers C, C, (see Figs. 3, 4, 7 8' and 10) firstreceive the yarn elements from the spool and guide them between pairs.offlanged and spring pressed guide rollers C C? and R R the spring Rproviding a predeterminedv amount of tension, and thence to the flangedguide roller C O? rotatably mounted upon the radial rods 0 C The rods 0extend across the faces of the reels and are spaced out" from the ,facesof the reels and from each other so as not to interfere with eachother'as the reels revolve in the opposite directions. For conveniencein gaining access tothe spools the rods G are set substantially directlyover each other on reels rotating in the same direction. If the rods arespaced out too far apart or not far enough apart the yarn :ele'-- mentswill overlap, depending upon lthewidth of said elements and the diameterof A coiled spring N mounted upon a stem IN and adjustable by the setcollar N operates the sleeve N to which is attached a pressure finger Nwhich rests upon the spool of yarns and exerts a'constantly decreasinamount of pressure upon the spool,

as the diameter of the spool decreases, and hence provides a practicallyconstant tension upon the yarns ,as they. pass to the mandrel. 1

The channels F F5 are so {expansion-of thefabric has thefurther useful arranged as to bind the yarn elements and -i revent themfrom slipping or' drawing side .w1 se out1of proper alinem'ent and yetper-' -m1tt1ng them'to, be pulled 'freely; ofi' from broughtasinejartofthe' surface of the mani drel A asjthe angle of winding will permitand are spaced apart at a'predetermined dis- The yam elementsare;guidedto the hel mandrel' A by means described, and.

by meansjof the pipe The forward extremity of the mandrel is free forthe pasvalve is operated by rods F F which pass through stufing boxes FF in the hollow head F into which the inlet pipe 'D 'for rubber leads.Openings-F permit the coating material to surround the valve so thatitwill not stick. A guide tube W permits the passage of a. metallic core Winto the hollow mandrel A when it is desired to insert the core intothefabric band. QT-he metal core passes through a stufing box W and. iscoated in the hollow mandrel. These rods F F are manually operated by across bar F 9 allowing the passing of rubber through the mandrel whenthe ,valve F is opened, and shuts ed the flow of rubber when the valveis closed.

The preferred form of hollow mandrel is clearly shownin Figs. 11, 12,16, 17, 18, and 19, where A' is the cylindrical portion over which thefabric band is drawn and upon which the fabric is constructed, asdescribed above. A, A are oppositely placed lateral extensions orwidened portions of the man- 'drel located. thereon within the coatingchamber, and A, A are similar oppositely placed extensions upon themandrel formedpreferably at right angles to the extensions A, A; Themandrel flattened at itsextended or widened portions and also at itsouter extremity/l, passes through the rubber receptacle and asthe fabricband passes over these extensions it is'first expanded in one directionand afterward in another,- which .hasthe useful efiect of temporarilyseparating the fibrous strands and elements so that the rubber coatingwill have access to and coat the entire exposed surface thereof. The

efi'ect of temporarily changing the relative angles at whiclijthe yarnelements cross each other and thereby exposing the surfaces of the"crossing points to'thevcQating-material, so

tremities inclined and. slightly-overlap the extremities of theadjacent'pair ofe'xpanding' devices. construction enables the fabnc'to pass 1-: yfrom one set ofexpanding devices to another and to remain under acertain amount of tension all .the time. 7

The liquid rubber 'or other adhesive material is stored in suitabletanks 5, connected with suitablepumps J J, to the pipes D and Drespectively. The rubber applying receptacle 1, (Figs. 16, 21,and22) ispro- Videdwith a resilient closure where the cylindrical portion of themandrel enters therein, consisting of guided slidin g sections F Fcontrolled by one or more springs F This closure makes close contactwith thefabric band as it passes over the mandrel into the rubberreceptacle, and prevents the liquid rubber from escaping, yieldingsufliciently to allow a knot or other small ob-- by means of a pullingroll P shown in Figs.

29 to 31 inclusive, over which it passes after leaving the coatingchamber, and by means of flexible metallic bands P and P between' whichit is compressed. In order to grip the fabric band firmly and notsqueeze out the coating material therein, the upper metal mand P isprovided with projectionsP P on its inner face as shown in Figs. 27 and28, which grip but do not injure the band. The upper metal band P passesover the guide rolls P P P, P and P and pulling roll P, and the lowerband P passes over the guide rolls P P, P and pulling vroll P, I and themetal bands inclosmg ,the fabric' band F between them pass between thestag vgered rollers P P which compress them tightly together so as tocarry the fabric band withthem. The lower band 1? separates from thefabric band F and the upper metallic band- P. on the pulling-roll P,while the upper metallic band P separatesfrom the" fabric band 'on theroll P the fabric band F then being carried over the drying roller Q,the drums Q, Q Q and the rollers Q, Q, and Q", Q by the metallic endlessconveyer band Q The construction and mode of operation of thedryingrollers and drums may be described as follows: Sprocket and roll Ptogether with chains W, W- rotate the pulling roll P. The three drivenrolls or grooved drums Q, Q and Q are operated to move in unison bymeans of the train of gears q, 9, g g and the shaft and the spiral-gearsQ 'HIId. g operated by the shaft R, which passes in the rear of themachine. The shafts Q of the'grooved I drums Q, Q Q are'parallel andinclined and over all the grooves of these drums passes the flexibleband or tape Qto which the extremity of the fabric band is firstattached until it has been wound over all the drums and rollers of-thedrying device, when it can be fed through the remaining devices of themachine. The endless flexible band or tape Q after passing around allthe grooves in the-drums Q, Q and Q and rollers Q, Q,

and Q is led around the idler rolls Q, Q, Q, and Q T'to'the roller Q inline with pulling roll P. The groove idler rollers-Q, Q and Q arerotatively mountedupon their bushings. At a point distant from thefirst'roller in the series, a nozzle R dis charges a coating ofpredetermined density upon the outer surface ofthe fabric band,

the amount being-regulated by. the needle valve R the coating beingsupplied through the pipe D from the pump J. The relative speeds of thepulling device and of the drying rollers and drums can be regulated toaccommodate the amount of shrinkage of the fabric band on the dryingdevice by means of the expansion pulley 2 (see Figs.

24, 25, 26, and 26) upon the driving shaft- R from which the shaftRwhich drives the drying mechanism receives its power. After passlng overthe drying rolls the band passes if desired through the vacuum chamberG. In the chamber G a vacuum 1s produced as nearly perfect aspracticable by suction through the tube H. In this chamber the"vsolvents in which the rubber coating has been dissolved are evaporatedto a predetermined degree. A coil of steam pipe H or any other suitableheating system-furnishes heat to assist in the evaporation of thesolvents from the liquid rubber .or other adhesive material used on thelaminated band.

In Figs. 35 to40 inclusive are shown the vacuum chamber and its inletand outlet gates. Here K and K are the upper and lower halves of theinlet and outlet gates inclosing rollers I I between which the bandpasses to exclude the outer air, the

lower half of the casing being madeslightly adjustable on the upper halfby means of aspring pressed pin K* and an adjusting screw K whichengages the spring K con- ,fined in an opening K in the bracket K therolls. The partial rings'K and K of arguto or other self lubricatingmaterial, since free oil would be detrimental to the I rubber on thefabric band, form bearings for the rolls K K The upper half of the gateKis secured to the wall of the chamber G by screws K", K, while the lowerhalf of the gate K is adjustably securedto theupper half K by gibs K11",K which he held by screws'K 4 K After passing through the drying.chamber the fabric band passes through a stretching device shown inFigs. 1, 2, and 41 to inclusive. HereT, T are grooved rollers, one ofwhich'T is larger than the other, over which the fabric band passes, andby means of which a certain amount of stretching capability is removedfrom the band. The result of this operation is to produce a band havingthe exact amount of stretching capability left in it which when it isincorporated in the fabric will make the fabric capable of expanding tothe desired degree. To effect this result the band first passes over thesmaller roll T and next over the larger roll T and is compressed againstthe grooved surfaces of the rolls by means of the smaller guide rolls T?and T and spring pressed levers T ,-T Adjustment of presv sure is madeby the rods T T over which the springs T, T are sleeved, being screwedinto the standards T, T and locked in position by the nuts T T T and Tare flanged idler guide rolls. The rollers are operated by means ofsprocket chains T sprocket wheels T, T and idler T spur gears T, T T Tand bevel gears T T and rear shaft R. Details of the lever and springtension are shown in Figs.

and 45.

After passing through the stretching device the fabric bandis wound uponand X' shown in Figs. 1, 2, and 46, which is operv ated by means of theshaft R and bevel gears;

X and X and a band of Holland cloth or metal mounted upon-an adjacentreel Yr -is interposed between the layers of the band to prevent themfrom sticking together. The reel X is driven by the spring ressed key X'in the shaft X engaging the caring surface X of the reel X. Themechanism for operating the variousportions of the devices are asfollows: 6 is the main drive shaft. This shaft through clutch 24'operates the reel driving shaft 7 standard 15. By changing gear 11-mounted on the lever 65, the reels may be driven at which in turnoperates the reels through the bevel gears 8 and 9. The shafts 6 and 7are. operatively connected by means of spur gears 10, 11, 12, 13 and 14mounted upon a different speeds for winding the yarn elements atdifierent angles. R is a shaft mounted upon the standard 15 and is oper-'ated from the main shaft 6 by the spur gears 31, 30, 29', 28, and 1 4.Shaft R maybe i driven at different speeds by changing gear 30 mountedon the lever 66. The shaft W is also mounted on the standard 15 and isoperated from shaft R by bevel gears 41 and 40. The propelling roll P isactuatedfrom shaft W and therefore diflerent speeds of propelling" thefabric band on the tieacvi mandrel may be obtained by substitutingdifi'erent gears in place of gear 30. The

-shaft R is driven from the shaft R by means of the expansion pulley 21and pulley 22 and belt 23. A belt 50 from the main shaft and pulleys 51and 52,- operate the pressure pumps for rubber. Two pumps are employed,one of which supplies fluid coating material to the inside of thetubular -m'andrel and the other provides fluid coating material to thenozzle which coats the exterior of the fabric band, and also to the bevaried to suit the shrinkage of the fabric band on the drying rolls Q, QQ and drums Q, Q Q the pulley 21 is made expansible by means of a splitrim having inwardly inclined conical surfaces R against which a flangedhead R engages to spread the free end of the split rim. The flanged headR is longitudinally adjustable upon the screw threaded shaft R, A sleeveR keyed to the shaft R cooperates with the movable head to spread therim, and the rim is caused torotate by means of the pin R engaging theslot R in the sleeve R The suction pump 60 exhausts the air from thevacuum chamber G, through the pipe H and is operated by a belt 61 fromthe main shaft6 moving over pulleys 62 and 63.

In Figs. 1, 2, 47, 48, 49, and 50 are shown the detail structure of thepumps J, J.

a common worm J ,'and J J are the rotating gears whose teeth act asplungers to force the coating material through the pipes which lead tothe mandrel and exterior coating device respectively J is the standardwhich supports the pump casings J 5, J The valves J J regulate thepressure-of the rubberin the pipes D and D "by means of the spring J andthe screw I threaded, rod J which is adjusted so that when the pressurein the pump reaches a predetermined amount the valve J lifts and allowsthe excess rubber to flow back into the tanks 5.. i

It is evident that in this machine any desired form of material other.than that herein specifically described may be used as the' constituentelements of the fabric band. It is also obvious that any suitableadhesive substanceniay be used to coat the elements 'composing thisfabric'band and may be applied at any predetermined high temperaturewith or without vacuum for solidifying the same, without departing fromthe spirit of the invention or scope of the claims.

I do' not confine myself to the exact arrangement of the variousmechanical parts, provided any modifications would be of materialadvantage in the development and perfection of the machine as outlinedby the drawings and, specifications of this machine, nor do I confinemyself to the use of a liquid rubber or'other liquid adhesive material,but may use this rubber or otheradhesive material in any other formdesired.

for the purpose indicated.

It is evident that wherever it is desirable, for the purpose of reducingthe friction of the yarn elements while being interwound and laminatedon the forming tube to form a fabric band or for softening the coatingmaterial on the yarn elements or on 'the fabric band as it passesthrough the various coating devices or other parts of the 1 machine, anysolvents such as naphtha, benzol, gasolene, etc., according to thenature of the coating material used, may be applied in any desiredmanner, without departing from the spirit of the invention or a scope ofthe claims.

. It is obvious that one or more of the four reels may not rotate, sothat a predetermined number of the yarn elements may be laid parallel tothe longitudinal axis of the mandrel, while the remaining wheels rotateand wind the yarn elements on the mandrelat a predetermined angle,without departing from the spirit of the invention or scope of theclaims. It is also evident that the reels may be mounted singly insuccessive positions along the mandreland rotate thereabout when a highspeed of rotation and production is required for, certain bands in whichthe yarn elements are wound at a wide angle, without departing from thespirit of the invention or scope of the claims.
